4 Claims.

The present invention relates to cellular cartons of the typecustomarily employed for packaging fragile articles such as eggs, andhas particular reference to an improved type of egg car- 5 ton which maybe set up or erected from collapsed condition by hand.

A principal object of the invention therefore may be said to reside inthe provision of an easily erectable cellular carton.

An additional object is to provide a particularly strong cushion cartonwhich does not depend upon the use of disengageable hooks and slots forits erection.

A still further object of the invention is to provide a carton having asturdy support for the top and a cushion for the bottom.

'I'hese and other objects will be evident upon a consideration of thefollowing specification and with reference to the accompanying drawings,in

2o which L Fig. 1 is a perspectiveview of a carton constructed inaccordance with my invention;

Fig. 2 is a sectional view of the carton shown in Fig. 1 ln closedposition and taken along line 2-2 of Fig. 3;

Fig. 3 is a longitudinal section taken along line l A 3-3 of Fig. 2;

Fig. 4 is a top view of the carton in collapsed .condition and showing aportion of the longitudinal partition drawn away;

Fig. 5 is a view of the bottom of the carton in collapsed condition; and

Fig. 6 shows the blank from which the carton is constructed. 5 As shownin the drawings, the main portion of the carton is constructed from asingle blank which is cut, scored and folded to form a coverlockingstrip IU, a cover Il, a rear wall I2, a rear bottom section I3, a rearlongitudinal partition 4o section il, a front longitudinal partitionsection ii, a front bottom section i6, a front wall Il,

cross parti'tions I8, vand an attaching strip iii,

Each element of the carton is separated from the adjacent elements bysuitable score lines.

A carton which has met with considerable fayvor in the industry consistsof front and rear walls joined at their lower portions by a bottommember which is pressed upwardly along its cen- 50 tral portion intocushion-forming position, the

bottom member being engaged to cross partitions by hooks on the crosspartitions extending through slots in the bottom member. While thiscarton is highly effective from the standpoint of 55 the user. itrequires the use of a machine or block for setting up the carton fromthe collapsed condition in which it is received by the user.

In accordance with the present invention, the

bottom and longitudinal partition-forming sectiom are provided withslots 2li positioned Ito re# s ceive each of the cross partitions. Thecarton is folded along the score line between the bottom sections andthe lower'portions ofthe yfront and Y- rear walls, and the attachingstrip Ilis glued to4 the rear wall. The cross partitions Il are in- 1oserted through the slots 2l and, in the collapsed condition shown inFigs. 4 and 5, these cross par.- titions overlie the longitudinalpartition-forming sections. 'I'hat is. the vlongitudinalpartitionforming sections lie between the topA of the car- 15 ton andthe cross partitions. v

After insertion of vthe cross partitions through the slots 20, one ormore glue strips 2l are attached to the longitudinal partition-formingsection as shown in Fig. 4. In this manner the Ion- 20 gitudinalpartition-forming` sections are entrapped on the upper side of the crosspartitions.

The. cross partitions are provided with downwardly extending slots 22which preferably are of a depth substantially equal to the width of 25the strips 2l. To erect the carton from the collapsed condition shown inFigs. 4 and 5, it merely is necessary topress the longitudinalpartition- -forming sections together, as by means of the strips 2l.That is, the llongitudinal partition 30 sections are brought togetherand simultaneously raised so that the edges of the strips 2| pass overthe tops of the cross partitions! This motion causes the walls of thecartons to be positioned in an erect manner and also causes the crosspartitions to rotate into vertical position. When the attaching strips2| and the longitudinal partition sections are brought completelytogether the same may be'pressed downwardly into thel slots 22 on thecross partitions, thereby 40 forming the cartonv into the shape shown inFigs.

1, 2, and 3. In this position the glue strips 2i may rest on the bottomof slots 22 and the tops of the strips may be adjacent the top of thecontainer. The resulting structurewill form a rigid support for the topof the carton and eggs vcontained within the carton will besatisfactorily supported. Also, it will be noted that `the bottom of thecarton is divided up into independent units which oifer a greaterdegreeoflspring or cushion effect and at the Sametime jars* received byone of the sections vwill be less-readily transmitted to the adjacentsections than in the case of a solid bottom container. Thecrosspartitions may extend downwardly tosubstant'lally 55 the same levelas the lower portion of the carton, as shown in 1215.2, therebysupporting additional support for -the bottom.Itwillbeseenfromthedrawingsthatthedis mensions of the carton are suchthat the front Y and rear bottom sections plus the front and rearlongitudinal partition sections equal the width of [the cross partitionsplus the height of the front and rear walls below the points to whichthe lo longitudinal partitions are attached thereto.

'nais-construction permits the carton to be collapsed along the scorelines which separate the front and rear walls from the bottom sections.A .principal advantage of the container is that ll there are no separatepieces such as customarily are employed as the longitudinal partition inmany'hand set-up cartons, and the carton may be erected rapidly by handwithout the use of machines or blocks of any character. Buch de- S0vices may be employed if desired, and the ease of erecting the cartonmay be used to advantage in the machine set up. It will be understoodthat to close the carton the cover-locking strip Il is depressed intoengagement with the triangular ,all hinge portions along the front wallby which the cross partitions are secured. It will be noted that Y thecross partitions are cut away adiacent the upper ends of slots 22. Thisfacilitates the erection of the container, since it is necessary to Nraise the longitudinalpartition section as the sides thereof are broughttogether. The erection of the carton may be facilitated still further byA a more severe cutting away of the cross partitions. The glue strips 2lsecurely bind the car- 35 ton in the proper assembled condition and itis not necessary to depend upon individual attachable and detachablehooks'and slots.

'Ihe carton obviously may be changed in detail over the structure shownand described 40vherein for purposes of explanation, and all suchchanges and modifications are intended to be included in the appendedclaims.
